Waveform data diagnostic device, waveform data diagnostic method, program and waveform data diagnostic system

摘要

The waveform data diagnostic device (1) includes a data acquisition unit (11), an orthogonal transformation unit (12), a storage unit (13), and a waveform data diagnostic unit (14). The data acquisition unit (11) acquires time-series waveform data of the device (2) to be diagnosed. The orthogonal transformation unit (12) transforms the acquired waveform data into frequency components to generate frequency component data, and an orthogonal transformation execution unit (121) that generates two or more predetermined frequencies from the generated frequency component data. And an orthogonal region extraction unit (122) for extracting the specific frequency component data of. The waveform data diagnostic unit (14) includes two or more diagnostic execution units (141, 142, 143) that diagnose specific frequency component data of different frequencies based on the reference data stored in the storage unit (13), respectively. A synchronization control unit (144) for synchronizing the diagnostic results of (1) and a diagnostic result output unit (145) for outputting diagnostic result data indicating the synchronized diagnostic results.
